Constructor & Destructor Documentation

__init__()

pancake.tapestack.TapeStack.__init__	(		self,
		Basecurve	curve,
		int	numtapes,
		float	tapewidth,
		float	tapedistance,
			t = None )

Member Function Documentation

_points_to_rectangle()

pancake.tapestack.TapeStack._points_to_rectangle ( P, corners, R )

staticprotected

Minimum distance from points P (p, 3) to the rectangle given by its corners and frame R.

clearance()

pancake.tapestack.TapeStack.clearance	(		self,
			min_arc_distance = None )

Smallest distance between stack cross sections that are far apart along the curve.

Returns (distance, i, j) for the closest pair of stations with
|t_i - t_j| > min_arc_distance (default: twice the stack diagonal).  A
distance below zero cannot occur with this estimate; a value close to
zero (below one tape distance, say) means the tapes cross or touch.

envelope()

pancake.tapestack.TapeStack.envelope

(

self

)

Corners (m, 4, 3) of the rectangle enclosing the stack at every station.

plot()

pancake.tapestack.TapeStack.plot	(		self,
			ax,
			tapes = None,
			every = 1,
			color = "k",
			lw = 0.4,
			sections_every = 0,
			section_color = "tab:orange" )

Draw the tips of the tapes as lines and, optionally, the stack envelope at some stations.
